The IP Video over DOCSIS approach uses the C4/c CMTS to send managed IP video packets over a DOCSIS delivery system
via the Hybrid Fiber Coax (HFC) network. This is the way that IP packets are transported from the head-end to the home.
Some of the benefits of IP Video over DOCSIS are:
Increased number of programs that can be offered due to Statistical Multiplexing Gain resulting from DOCSIS 3.0
Channel Bonding
High availability characteristics provided by the C4/c CMTS can be extended to IP Video
Channel efficiencies resulting from Switched Digital Video-like (SDV-like) operation provided by the dynamic activation
of service flows and IP multicast streams within the C4/c CMTS
The C4/c CMTS QoS functionality that manages and limits the bandwidth of third-party IP Video content from the
Internet allows that content to be safely multiplexed into the mix of the MSO-managed video streams.
